3 — Replace a G-241W-A indoor ONT
3-6 Alcatel-Lucent 7368 ISAM ONT
Edition 01
I-240W-S I-241W-S I-241W-U Product Guide
9 If required, have approved service personnel who are trained to work with optic
fiber clean the fiber optic connection. See the 7368 ISAM ONT Configuration,
Management, and Troubleshooting Guide for more information about fiber optic
handling, inspection, and cleaning.
10 Connect the SC/APC fiber optic cable directly to the SC/APC adapter; see Figure
3-1 for the location of the SC/APC adapter.
11 Install the power supply according to manufacturer specifications.
12 Connect the power cable with an 8-pin Molex connector to the power supply.
Note 1 — Observe the following:
• To comply with FCC standards, use either RG-6 or RG-59 coaxial
cable. Also, proper attenuation must be inserted at the coaxial
output to guarantee that at the end of any coaxial drop, every video
signal is below 15.5 dBmV and audio signals are below 2.55 dBmV
(per channel).
• You may need to install the 75-ohm coaxial F connector on the video
cable.
Note 2 — Observe the following when connecting the F-type coaxial
connector to the coaxial connector on the ONT:
• Fully tighten the F-type connector on the cable by hand before using
a wrench to complete tightening (up to a maximum of an additional
1/8 turn). If using a torque wrench (as is recommended) to tighten
the connector, the torque setting should be between a minimum of
20 in-lbs and a maximum of 40 in-lbs. The connector should be tight
enough when the task is complete that it can not be unscrewed by
hand.
Danger — Fiber optic cables transmit invisible laser light. To avoid eye
damage or blindness, never look directly into fibers, connectors, or
adapters.
Danger — Fiber cables transmit invisible laser light. To avoid eye

Warning — Be careful to maintain a bend radius of no less than 1.5 in.
(3.8 cm) when connecting the fiber optic cable. Too small of a bend
radius in the cable can result in damage to the optic fiber.
Note — Fiber cable preparation varies depending on the type and size
of the inside or outside plant fiber cable being spliced to the SC/APC
fiber optic pigtail cable.
